    Methods of singlet oxygen generation and detection for understanding photodynamic processes
    (Wydawnictwo Uniwersytetu Rzeszowskiego, 2018) Ożóg, Łukasz; Aebisher, David
    Introduction. Photodynamic therapy (PDT) is a clinically approved therapeutic procedure that exerts selective cytotoxic activity toward malignant cells. Aim. Our goal is to present the PDT procedure which involves administration of a photosensitizing agent followed by irradiation at a wavelength corresponding to the absorbance band of the photosensitizer and energy transfer to ground state oxygen to generate cytotoxic singlet oxygen Material and methods. Analysis of literature. Results. In this paper we described the basics of PDT and lifetime of singlet oxygen in different media.

    Physical fatigue measured by functional MRI
    (Wydawnictwo Uniwersytetu Rzeszowskiego, 2018) Truszkiewicz, Adrian; Aebisher, David; Ożóg, Łukasz; Bartusik-Aebisher, Dorota
    Introduction. Physical fatigue is a physiological condition that can be measured by functional Magnetic Resonance Imaging (fMRI). Aim. Therefore, this work aims to present the research results currently reported in the scientific literature between the years 2014 and 2018 in the field of chronic fatigue syndrome using the functional MRI method. Material and methods. Analysis of literature. Results. We reviewed here the differences between temporary and chronic fatigue.

    The usefulness of relaxation time using MRI measurements
    (Wydawnictwo Uniwersytetu Rzeszowskiego, 2018) Bober, Zuzanna; Aebisher, David; Truszkiewicz, Adrian; Ożóg, Łukasz; Bartusik-Aebisher, Dorota
    Introduction. Magnetic Resonance Imaging methods are now frequently used for the analysis of the diseased tissue. These methods are based on the fact that the spin-lattice, T1, and the spin-spin, T2, relaxation times are different in diseased tissue as compared to that of normal tissue. Aim. Here we present measurements of spin-lattice relaxation time T1 on a Magnetic Resonance Imaging scaner with field strength 1.5 Tesla. Material and methods. Measurements of T1 relaxation time and analysis of literature. Results. We provide procedure for measurements of T1 relaxation time with field strength 1.5 Tesla and present a discussion of current applications.
